,Section A - Cellular Adaptation Injury AND Death
Q1.
In a mouse model of sepsis, genetic deletion of caspase-1 in macrophages unexpectedly
worsens survival despite reduced IL-1 and IL-18. Which compensatory mechanism best
explains this paradoxical outcome?
A. Upregulation of pyroptosis via B. Increased IL-1 secretion through a
caspase-11 and gasdermin D, leading to caspase-8-dependent non-canonical
enhanced membrane rupture and pathway that sustains fever and vascular
inflammation leakage
C. Loss of caspase-1-mediated cleavage of D. Enhanced activation of the NLRP3
gasdermin D, preventing membrane pore inflammasome through a positive feedback
formation and thereby reducing bacterial loop, amplifying IL-1 release and neutrophil
clearance recruitment
Correct: A - Upregulation of pyroptosis via caspase-11 and gasdermin D, leading to
enhanced membrane rupture and inflammation
Rationale:Caspase-1 deletion does not block pyroptosis entirely; caspase-11 can still cleave
gasdermin D in response to cytosolic LPS, causing pyroptosis and inflammation. This
worsens sepsis by promoting excessive membrane rupture and cytokine release. The other
options incorrectly suggest reduced pyroptosis or non-canonical IL-1 secretion that does not
compensate.
Q2.
A researcher observes that a tumor cell line with high PD-L1 expression becomes
susceptible to T-cell killing after treatment with an inhibitor of the deubiquitinase USP8.
Which molecular event is most directly restored by USP8 inhibition?
A. Surface expression of MHC class I B. Lysosomal degradation of PD-L1,
molecules via increased peptide loading reducing its availability on the cell surface
C. Nuclear translocation of NF-B, leading to D. Activation of the STING pathway through
pro-inflammatory cytokine secretion cyclic GMP-AMP synthase (cGAS) sensing
of cytosolic DNA
Correct: B - Lysosomal degradation of PD-L1, reducing its availability on the cell surface
Rationale:USP8 deubiquitinates PD-L1, preventing its lysosomal degradation. Inhibiting
USP8 promotes PD-L1 ubiquitination and degradation, reducing surface PD-L1 and relieving
T-cell suppression. The other options are unrelated to USP8's known role in PD-L1 stability.

Q3.
In a cohort of patients with chronic kidney disease (CKD), serum fibroblast growth factor
23 (FGF23) levels rise early, before phosphate retention. Which of the following best
explains the physiological rationale for this early elevation?
A. FGF23 directly stimulates renal B. FGF23 secretion is triggered by a subtle
1-hydroxylase to maintain active vitamin D increase in filtered phosphate load,
levels despite declining GFR promoting phosphaturia to preserve
phosphate balance
C. FGF23 compensates for reduced renal D. FGF23 acts on the parathyroid gland to
clearance of phosphate by increasing suppress PTH, preventing secondary
intestinal phosphate absorption via vitamin hyperparathyroidism in early CKD
D
Correct: B - FGF23 secretion is triggered by a subtle increase in filtered phosphate load,
promoting phosphaturia to preserve phosphate balance
Rationale:In early CKD, FGF23 rises to increase phosphate excretion per nephron,
maintaining serum phosphate within normal range. This occurs before overt
hyperphosphatemia, driven by a slight increase in phosphate load per remaining nephron.
The other options misrepresent FGF23's actions: it suppresses 1-hydroxylase and does not
increase intestinal absorption.
Q4.
A 45-year-old man with a history of alcohol use disorder presents with jaundice, ascites,
and coagulopathy. Laboratory tests reveal elevated serum iron and ferritin, and low
transferrin saturation. Which of the following best explains these iron studies in the
context of his liver disease?
A. Hepcidin synthesis is upregulated due to B. Hepatocyte necrosis releases ferritin, and
inflammation, causing iron sequestration in impaired synthesis of transferrin leads to a
macrophages and reduced transferrin falsely low transferrin saturation
saturation
C. Alcohol directly enhances intestinal iron D. Portal hypertension causes splenic
absorption, leading to iron overload and true sequestration of iron, reducing serum iron
transferrin saturation elevation but increasing ferritin as an acute phase
reactant
Correct: B - Hepatocyte necrosis releases ferritin, and impaired synthesis of transferrin
leads to a falsely low transferrin saturation
Rationale:In advanced liver disease, hepatocellular damage releases ferritin, and reduced
synthetic function lowers transferrin production. This results in high ferritin with low transferrin
saturation, mimicking iron overload but reflecting liver dysfunction. Inflammation can increase
hepcidin, but that would lower iron and ferritin, not elevate ferritin to this degree.
